Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FAD3M32 is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.32 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Package configuration: Axial through-hole
• Physical dimensions: 0.093" Dia x 0.250" L (2.35mm x 6.35mm)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The identified substitute part RNF14FTD3M32 maintains complete electrical and mechanical equivalence. The only difference is the packaging format: the main part is supplied in Tape & Box (TB) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both parts are manufactured by Stackpole Electronics Inc within the RNF series and carry identical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both RNF14FAD3M32 and RNF14FTD3M32 are active production components from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and supply chain logistics:

• RNF14FAD3M32 (Tape & Box): Suitable for applications requiring boxed component delivery with tape packaging for automated assembly processes
• RNF14FTD3M32 (Cut Tape): Suitable for applications where cut tape format is preferred for component handling and inventory management

Both parts deliver identical electrical performance and mechanical compatibility. The choice between them does not affect circuit functionality, thermal performance, or regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD3M32 be used as a direct replacement for RNF14FAD3M32?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Box). Circuit performance, tolerance, temperature characteristics, and compliance certifications are identical.

Q: What determines substitution eligibility for this resistor?

A: Substitution is valid when the following parameters match: resistance value (3.32 MOhms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and axial package configuration with identical physical dimensions (0.093" Dia x 0.250" L).

Q: Does packaging format affect circuit performance?

A: No. Tape & Box (TB) and Cut Tape (CT) packaging formats are delivery methods only. They do not affect the electrical specifications, thermal performance, or reliability of the resistor component itself.

Q: Are both parts compliant with current regulations?

A: Yes. Both RNF14FAD3M32 and RNF14FTD3M32 are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.

Q: What is the temperature coefficient significance?

A: The ±100ppm/°C temperature coefficient indicates the resistor's resistance change per degree Celsius within the -55°C to 155°C operating range. Both substitute parts maintain identical temperature stability characteristics.
